I can't vote... because I'd not want any of those items to come up on a search for me, and the poll won't let me register a vote without anything checked...
Seriously, there are only a couple of those I'd feel comfortable sharing with anyone I didn't already consider at least a very close friend or family - and at least half of those items I'd not share with anyone.
Good article --
this/ one is the one that really caught my attention as to how this sort of information can add up to expose things that you'd rather not divulge. It's the one where Target started targeting advertisements for baby products to a teenage girl, because her purchase history gave them a strong indication that she was pregnant (she was). And that's how her parents found out.
I'm pretty anti-tracking. It's getting harder to avoid, though. My most recent pet peeve is that grocery stores (and others, likely) are starting to only have sales apply to people who use their "loyalty cards". And they advertise the "sale price" when it's not actually the price for anyone else. Grr.
I'm rather lucky in that regard... my name is pretty common, and it's basically impossible to get information on me from Google with that alone. Even if you know where I live, you'll not get anything that's actually me.
